A coiled spring l7, ha ving one iend connected (to the lever l3 and the other end to the frame, serves to retmetathe lever afterit hasbeen attracted bythemagnet and through the engagement 0f the dog :with the ratchet 12 cause therotation of the ratchet one step. Asuitable' spring-pressed dog 18 also engages the teeth ofthe ratchet 12; to

haft I I The hour wheel 2 is loosely mounted on the shafti and is provided with twenty-four printing ifiacets whereby two sets of hourindicating'imimerals :may'be presented. As i more clearly' sho-wn in'Fig. 8, these twosets,

of; the hour figures are alternately arranged, one set, as at 119, being in normal reading position: and: theialternate set, as at -20, ha ving an abnormalwposition. :In theillustration, instead ofibeingarranged vertically, so that the impression :on :the time card would he madevertically, thefigures of the set 20 are arrangedto printhorizontally 0n the card, so that when the impression is made by this set aglance will snflice to show that: theoard has an irregular time printed on it. This hour wheeljunder normal conditions is adapted tobe rotated step by step: to present the normal printing-fig ures. 'ln iotheriwords, then ormal rota'tive step oft-he Wheel is twicertlie distancei of a single; figure ;'j-so that, for illustration, assuming-thatthe 57' has been printedjflthe next rotative step will carry the wheel; sufficiently far around to! present *the normal pnevent back lashofthe 8 to printing position. The rotation of the hour wheel is accomplished by a twotoothed gear 21 mounted on the shaft 10 and adapted to rotate therewith and advance the hour wheel a full step eachhour. The wheel 21 is provided with two teeth 22 adapted to mesh with a pinion 23 mounted on the shaft 24:. This pinion has integrally formed therewith a spiral pinion 25 meshing with a spiral gear 26 connected with the hub 27 of the hour wheel 2, so that each impulse imparted to the pinion 23 by the gear 21 will be transmitted by the spiral pinion 25 to the spiral gear. 26 and the hour wheel will be rotated one step. The day wheel 8 is rotated from the hour wheel, and to this end on the hour wheel hub 27 there is mounted a single-toothed gear wheel 28 meshing with a pinion 29 on a shaft 80, which is provided with a second pinion 31 meshing with a gear wheel 32 mounted on the hub of the day wheel, so that upon a complete rotation of the hour wheel 2 the day wheel will be ad vaneed one step.

111 a timeindicating apparatus of this character it is desirable to be able not only to indicate the regular In and Out time of the employees, but also to indicate abnormal In and Out time of the employees, and particularly the late In time of an employee. This indication preferably should be such that it not only shows the time of entering but also shows this time in such a manner that if the employee enters late the time-keeper, in looking over the cards, can tell at a glance when such lateness occurs. It is also advantageous that the space occupied on the time card in making such indications should be no greater than the spare occupied in making a normal impression. To this end I have provided a different set of hour impressions for use when the employee enters late. This set of impressions is changed automatically when the late period commences' As, has been heretofore referred to, the hour wheel is provided with the two sets of time indicators, the normal indicators at 19 and the abnormal indicators at 20. These abnormal.indicators are intended. for use when the employee cheehsin late, and means are provided to" autonmtieally shift them into indicating position, this means beingadjustable so that they can be caused. to be shifted at any period. This shifting vis accomplished by rotating independently of the regular impulse rotation the hour wheel a half step, which will thereby bring the abnormal indicators into position, so that as the hour wheel is rotatedthey will be brought oppositev the printing 01" indicating point. Afterthe time for which it is desired that these abnormal indicators indicate or print has elapsed... the hour wheel is then shifted so that the nm'mai.

' indicators will .be broughtinto printing position by the rotation of the hour wheel. This shifting is accomplished by means of the worm pinion 25 and worm gear 26. The pitch of the teeth of these members is such that when the worm pinion 25 is shifted laterally it will cause the gear 26 to be advanced or retracted. The pinion 25 and the drive pinion 23 are slidably mounted on the shaft 24 and are shifted laterally by means of the double cam 38 mounted on the shaft 34 and rotating with said shaft. A roller or pin 85 mounted on the lever 36 engages in the cam groove 37 of this cam wheel 33. This lever is pivoted to the side member 6 at 38 and its opposite end is provided with teeth 39 adapted to lit in the grooves formed between the rings -10. which are mounted on the same hub as the pinion 23 and worm pinion 25, so as to rotate therewith.

It is seen from the above construction that a partial rotation of the cam wheel 33 will cause the lever to shift to the right or left, thereby shifting the worm pinion 25 to the right or left, so as to cause the gear wheel 26 to be advanced or retracted. The pitch of the worm threadsof the pinion 25 and gear 26 is such that a complete movement of the pinion 25 to the left, loolcing at Fig. l, will advance the hour wheel one half step, bringing the abnormal printing :l'acets into position, whereby they will be presented to printing position, and a complete shift of the worm pinion 25 in the opposite direction will rotate the hour gear backwards a half step, so that the hour printing wheel will be in normal position. The shaft 34: at its outer end is provided with a pinion 41 adapted to mesh with and be driven by a gear 42. Mounted on the shaft of this gear 42 is a ratchet wheel 43. The teeth of this ratchet wheel are adapted to be engaged by a pawl 4.4.- mounted on the end of a lever eh) pivotei to the side member 11 at 46. F or preventing back lash of the ratchet all, a springpressed pawl 4.7 is provided. to also engage the teeth thereof. The lever 4:6 is provided with a cam projection -18 adapted to be engaged by one or more of the adjustible rains l9 mounted upon and rotating with the gear wheel 50. This gear wheel is driven by a pinion 50? mounted on a shaft 50* on which is also mounted an idler 5'1 meshing; with a pinion 52 on the sha l t it), the gear Fl, being thus operated in. timed relation with the hour printing wheel. I preferably picvide a plurality of cam members on the when! 50 and provide for adjusting these cam nienr bers to any desired position. The wheel is provided with hour graduations 55". and the space between is divided into quarter-hour graduations. Of course, any finer division or a dilferent division of the gz raduations may be provided, if desired, these graduw tions being provided so that the cams may beset at the proper intervals; These cams comprise. small fiat barsrof material having one face inclined, and at their inner ends these barsiareiprovided with circular pins 54 ad-aptedto fit in an annular groove 55 (Fig. 6-): cut in the face of the wheel 50. A clamping ring 56 is secured over the plates and held in position by means of s 'ews 57. By this'construction' the cam members 49 may be shifted. around the wheel to any dosired position, and those members which it is notdesirged to use may be rotatedon the pins 54 so that their upper ends lie below the periphery of the ring 56- and out of operative. position. These cam members in rotation engage the cammember l8 on the lever 45, raising the same, and after the wheel camv member has passed beneath the lever cam member, the lever is retracted by means of a coiled spring 59, causing the dog 4% on the end thereof to engage the ratchet wheel 43 and rotating the shaft 34, and with it the cam wheel 33, one step, to shift the pinion 25 to the right or left, asthe occasion may require. Opposite the time Wheels and arranged t-o-hold thetime card in a position toreceive the impression therefrom I provide a suit able card-holder 60,. and the impression on the card is made by a hammer 61-, which strikesthe back of the card. and causes the impression of the time-indicating wheels to be made through a suitableribbon 62- supported opposite the wheels, Tlhishammer (51 is pivoted at 62 to the bottom of the supporting frame and is caused to strike its blow by a spring. ,A bell crank lever 63 engages a cam wheel 64, which is rotated by a ratchet (Simounted. on the same shaft as the cam wheel and engaged by a dog 66 mounted on one end 67 of the bell. crank lever 68. The opposite leg 68 of the lever projects out andis provided with a handle, so that a depression of the lever 68 will. cause the cam 64 to rotate, throwing the arm 61 away from the time card, and as soon as the end of the lever 68 rides oil of the cam the spring will cause the lever to snap forward, delivering a hammer blow against the card and causing the impressionto be made. in (nieratiointhe circuit through the mag net is momentarily closed once every minute.

This rotates the shaft 10, thereby advancing the minute wheel 1 once every minute and causing a new facet to bebrought opposite the printing point once every minute. The wheel 21, through the. pinion 23, the worm pinion and the worm gear. 26,. advances the hour wheel one step once every hour, thereby bringing a new facet opposite the printing position once every hour.

For the'purpose of illustration we will assume that the lunch. hour isbetween 11 and 12 oclock. It is, therefore, desirable after 12 oclock to show the time in a different manner, so that the card will indicate at a lance that persons entering after 12 oclock will have passed one another and the lever d5 retracted by the spring 59, causing the ratchet to be rotated one step and partially rotating the shaft 34 and with it the cam Wheel This rotation of the cam wheel will swing the rear endof the lever to the left, or to the right, looking at. Fig. i, shifting the spiral pinion 25, and due to the spiral threads of this pinion the spiral gear 26 will be rotated, advancing the hour wheel one half step, so that the abnormal numeral 12 will be brought in printing relation to the parts, whereby for as long. a period of time as desirablewe will assume until 2 oclock-the hour will be indicated by cam will engage the cam member 45, causing another stepped rotation of the cam wheel and moving the spiral cant transversely inthe opposite direction, so that the hour hand will be shiftedback a half step and the normal printing, facets will be brought into positionto continue to print as the wheel is rotated. I t

It is thus seen that by the proper positioning of the cam members 459 on the wheel 50 the hour printing Wheel may be shifted back and forth, whereby the abnormal and normal members can be brought into printing position by the continued time rotation thereof. y

While. I have described my device as having a different position for the abnormal. time-indicating member, it will be understood that these members have any suitable indiciathereonor that the abnormality of the character printed thereon may be indicated in any desirable manner, as by placing the figure as shownhorizontallyror, if desired, these figures may be inscript while the normal figures are in roman characters,
